NAME

SVN::Web::Diff - SVN::Web action to show differences between file revisions

SYNOPSIS

In config.yaml

  actions:
    ...
    diff:
      class: SVN::Web::Diff
    ...

DESCRIPTION

Returns the difference between two revisions of the same file.

CONFIGURATION

The following configuration options may be specified in config.yaml.

max_diff_size

If showing the diff (see show_diff), this determines the maximum size of the diff that will be shown. If the size of the generated diff (in bytes) is larger than this figure then it is not shown.

Defaults to 200,000 bytes.

OPTIONS

rev1

The first revision of the file to compare.

rev2

The second revision of the file to compare.

revs

A list of two or more revisions. If present, the smallest number in the list is assigned to rev1 (overriding any given rev1 value) and the largest number in the list is assigned to rev2 (overriding any given rev2 value).

In other words:

    ...?rev1=5;rev2=10

is equal to:

    ...?revs=10;revs=5

This supports the "diff between arbitrary revisions" functionality.

mime

The desired output format. The default is html for a diff marked up in HTML. The other allowed value is text, for a plain text unified diff.

TEMPLATE VARIABLES

at_head: Boolean, indicating whether or not we're currently diffing against the youngest revision of this file.
context: Always file.
rev1: The first revision of the file to compare. Corresponds with the rev1 parameter, either set explicitly, or extracted from revs.
rev2: The second revision of the file to compare. Corresponds with the rev2 parameter, either set explicitly, or extracted from revs.
diff: An SVN::Web::DiffParser object that contains the text of the diff. Call the object's methods to format the diff.
diff_size: The size of the generated diff (before parsing).
max_diff_size: The configured maximum diff size.

EXCEPTIONS

(cannot diff nodes of different types: %1 %2 %3): The given path has different node types at the different revisions. This probably means a file was added, deleted, and then re-added as a directory at a later date (or vice-versa).
(path %1 is a directory at rev %2): The user has tried to diff two directories. This is not currently supported.
(path %1 does not exist in revision %2): The given path is not present in the repository at the given revision.
(two revisions must be provided): No revisions were given to diff against.
(rev1 and rev2 must be different): Either only one revision number was given, or several were given, but they're the same number.
